The outer piston 35 may be a hollow cylindrical tube segment having a first end 205, a second end 210, an outer surface 212a, and an inner surface 212 b. The outer piston may be a copper alloy, such as brass or bronze.

Due to the inclined surface 222, the length of the outer piston 35 is not uniform and may range from the longest length 214a to the shortest length 214 b. The planar surface 220 of the first end 205 may include a recess 225 protruding from the planar surface 220. The recess 225 may be a semi-cylinder divided in two by the circular face of the cylinder, the recess having a flat side 230 and a curved side 235.

When the male member 60 and the female member 20 are coupled, the external pin 65 of the male member 60 may be fitted into the external socket body 40 of the female member 20. The outer pin 65 may contact and engage the recess 225 of the outer piston 35. The recess 225 may reduce the contact area between the outer piston 35 and the outer pin 65. The recess 225 may reduce contact stress between the outer piston 35 and the outer pin 65. The recess 225 may optimize hertzian stress between the outer piston 35 and the outer pin 65 during contact.
The outer pin 65 may engage the recess 225 of the outer piston 35 and compress the outer spring 30. The outer piston 35 may move with the compression spring 30 and may expose the center contact 45. The center contact 45 of the female component 20 may fit within the outer pin 65 and may engage the center pin 75 of the male component 60. The outer spring 30, when compressed, may apply a force 310 to the deflection surface 222 of the outer piston 35 at the longest side length 214a and may apply a second force 320 to the deflection surface 222 of the outer piston 35 at the shortest side length 214 b. Since the spring 30 is compressed by the deflection surface 222 of the outer piston 35 to a greater extent at the longest side length 214a than the deflection surface 222 of the outer piston 35 at the shortest side length 214b, the force 310 may be greater than the force 320. A force 310 greater than the force 320 may in turn apply a force 330 toward the outer socket body 40 at an end adjacent the longest side length 214a of the angled surface 222. A force 310 greater than the force 320 may in turn apply a force 340 toward the outer socket body 40 at the end of the shortest side length 214b and adjacent to the planar surface 220. The forces 330 and 340 may allow the outer piston 35 to slide within the outer socket body 40 with low contact resistance. The external piston 35 engaging the external pin 65 may facilitate contact between the center contact 45 of the female member 20 and the center pin 75 of the male member 60.

When the male member 60 and the female member 20 are coupled, the external pin 65 of the male member 60 may be fitted into the external socket body 40 of the female member 20. The outer pin 65 may contact and engage the recess 225 of the outer piston 35. The outer pin 65 may engage the recess 225 of the outer piston 35 and compress the outer spring 30. The outer piston 35 may move with the compression spring 30 and may expose the center contact 45. The center contact 45 of the female component 20 may fit within the outer pin 65 and may engage the center pin 75 of the male component 60.
As explained above, the outer spring 30 may apply a force to the outer piston 35 when compressed and may allow the outer piston 35 to slide within the outer socket body 40 with low contact resistance. The external piston 35 engaging with the external pin 65 may facilitate contact between the center contact 45 of the female member 20 and the center pin 75 of the male member 60 and may compensate for misalignment of the external pin 65 and the external socket body 40, e.g., coupling at an oblique angle. The external piston 35 may compensate for +/-0.3mm misalignment of the center contact 45 of the female member 20 and the center pin 75 of the male member 60 in the axial (X, Y) direction.
